Contributions summary:Leonor's contributions focused on implementing features within the `pkg/apiserver/rest` directory of the Grafana project. Their work involved the creation of a "dual writer" implementation, which writes to both legacy and unified storage backends. This involved creating several new files and modifying existing ones, specifically for mode implementations, as well as adding unit tests to ensure the functionality and reliability of the dual writer implementation. The user's contributions demonstrate a deep understanding of the backend system and how to integrate changes to different storage layers.
